Stop Guessing Who to Call. Start Knowing.
Sigma builds precision-targeted lead lists using AI, verified B2B databases, firmographic filters, and real-time intent signals. You get qualified contacts — not a spreadsheet of cold names.
Build Your Lead ListThe Prospecting Problem
Your sales team is spending hours building prospect lists from LinkedIn searches, outdated databases, and Google detective work. Half the contacts are wrong. Half the companies don't fit your ICP. By the time you have a decent list, the buying window has closed.
Sigma solves the sourcing problem. Instead of starting with a generic database and filtering down, Sigma starts with your ideal customer profile and builds outward — using firmographic data, technographic signals, and buying intent to identify companies that match your criteria and are actively in-market.
